There is a great deal that has been written about the ancient Celts. This is especially true among the Pagan community because many find that the myths and legends of the Celts strike a chord that rings true.
Sometimes, however, it is possible to see things backwards. By that I mean that because you do something a particular way today, you assume that the ancients did it either the same way or in a similar fashion. Ah, if only it were so!
That simply isn't good history. You have to get good information, not make assumptions. That's why I am very enthused with Douglas Monroe's The 21 Lessons of Merlyn.
When you read this book you will see that it was written by a person who is both a scholar and a bard. He instructs by way of stories, making the purpose and method of the philosophies, exercises, and magical rituals crystal clear and easy to apply, yet not limiting his brilliant research and scholarship. In fact, the teachings in this book are based on a manuscript which is now in the private collection of the Albion Lodge of the United Ancient Order of Druids of Oxford.
One of the things I really like is the traditional Druid triads, concepts that are broken down into thee short sentences. For example, the Three Virtues of Wisdom are to be aware of all things, to endure all things, and to be removed from all things. The three spiritual instructors of mankind are mastery of self, master of world, and mastery of unknown. You'll learn many of these and be able to discover how they are spiritually and practically meaningful in your life.
There is so much great material in this book that I can't say enough about it! Already, more than 120,000 people are using this book. If you want to find out what the Druids really did, and put it to use in your life, get this book.
